Application filed Qctoher 28, 1913. Serial No, 334,054.

To all w/wm'z t may concern:

Be 1t known that I. rimmer Kimmie, a citizen of the United States,and resident oi Newton, in the county of Jasper and State of Iowa, have invented a certain no i and useful CairStopper, of which the following is a specification. 7

The object of my invention is to provide a can-stopper of simple durable and inexpensive construction.

A. further object of my invention is to pro vide a stopper for the filling and outlet openings of cans, bottles, and other receptacles, which may be attached to the can, receptacle or the like and instantly moved to position for covering or uncovering the openings therein.

A. further object of my invention is to provide a compact arrangement of parts, adapt ed to occupy a minimum amount of space and arranged to be of sufiicient strength to resist accidental knocks against it. y

A further object of my invention is to provide a device adapted to automatically seal the opening in the receptacle and to automatically form a closure sealwhen the receptacle is accidentally jarred.

A. further object of my invention is to provide a sealing device for openings in receptacles, adapted to be readily attached to receptacles now in use without altering their form.

With these and other objects in view, my invention consists in the construction. urrangement, and combination of the various parts of the device, whereby the objects coutemplated are attained, as hereinafter norc Fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 shows a side elevation of the upper part of a can, havinga filling opening therein and a spout extending therefrom Fig. 2 shows a vertical, transverse. central, sectional view through. the device.

Fig. 3 shows a view taken on the line 3 of Fig. 1.

Fig. 4 shows a sectional view taken on the line lli of Fig. l, and

Fig. 5 shows a vertical. central, sectional transverse view of a modified form of my improved device, and illustrating the manner in which my device may be attached to receptacles which have not been specially made for use therewith.

Referring to the accompanying drawings, 1 have used the reference numeral 10 to in- Pa'tented Feb 15, 1921;.

dicate generally an oil can of welleknown construction, having a filliugopening comprising an upwardly extending collar 11 and a spent 12. ficlevis or yoke 13 has pins 14 pivotally mounted either end, the latter l'ieing passed through and secured to the neck or collar 11 by solder or a suitable washer 15. 1

The central portion oi the yoke has an opening therein designed to slidably receive a rod 16 having at its upper end a link 1? TllE'lOWQI'GHCl of the rod 16 is fixed "to a closure member designated generally by the reference nunierallS. The closure member 18 ispreferably of the shape of an inverted truncated cone, and composed of sheetmetal. iecurer to the upper web 19 of the number is a loop of wire 20. which extends be yond the member 19 at either end to form guideloops 21. The guide loops 21 are de signed to slidahly receive the sides of the yoke 13.'

Between the member 19 and the central portion 01" the yoke 13 is a spring 22. The neck 11' is preferably flared somewhat to correspond with the inclined side walls of the member 18 and to form a liquid-tight.

joint therewith.

From the construction of the parts just described, it will be seen that when my device is installed on a can or the like, the pressure of the spring 22 against the member 18 will cause a downward, yielding; pressure against the side walls of the neck 11, due to the coaction oi the yoke 13 and the pivots 1 1-.

I1 it is desired to remove the closure memberlS from the neck 11, the link 17 may be grasped and pulled upwardly which will lift the member 18 clear from the upper edges of the neck 11, thereby making it possible to swing the yoke 13 to one side of the neckfwhere the pressure of the spring will force the bottom of the closure membera-gainst the side of the neck and yieldinpgly hold it from movement or vibration.

V7 hen the parts are in the position shown in F 2, it will be seen that vibration or jar imparted to the can 10 will merely cause the spring 22 to force the closure member 18 more tightly into the neck 11, thereby automatically increasing the liquid seal, as

the tendency. to leakage due to splashing of necks adapted to coact with threaded sheet metal caps.

spring 22, and the rod In this form of device,'the neck 11 is provided at its lower end with threads 23, designed to coact with threads 24L formed in the neck 25 provided with the'can.

In order to install this form of the device upon the receptacle, it is merely necessary to'remove the cap, which comes with the vessel or can and to screw the neck 11 down on the neck of the can. f

Fig. 5: also illustrates a slightly difl'erent form of closure member, wherein a substantially cup-shaped member 26 receives the 16 and is provided with an outwardly extending flange 27, having slots therein designed to slidably .receive the sides of the yoke13. 1 From the foregoing description of my improved device, it will be seen that I have provided a'stopper for cans, receptacles-or the like, whichmay either be provided with the receptacle when the latter is manufactured or may be readily attached to the receptacle after it is manufactured.

' In this connection, attention is called to the fact that a band adapted to be removably mounted onthe neck of a bottle may be readily substituted for the threaded portion '23 shown in Fig. 5, so that-the device may be readily secured to" a bottle.

I have also provided means whereby vibration or jar imparted to the vessel upon which'my, device is attached will automatically cause the closure member to seat 1t-.

my improved device, without departing from the essential features and purposes of my invention, and itis my intention to cover by my claim any modifiedlforms of structure or use of mechanical equivalents whlch may be rcasonabiy included within its scope;

I claim as my invention: Ina device of the class described a cup shaped stopper member having opposite. prqectmgears a yoke havlng arms projecting through said ears for slidably supporting the stopper member, a rod slidably mounted in the central portion of said yoke and secured to :the bottom of said cup shaped member, a spring mounted on said rod between said yoke and the bottom of" said cup partially received in the cup shaped member.
